RF receiversLow-cost, low-consumption receiver with a 3 volt (± 10%) supply voltage, narrow RF band, high immunity to supply noise and low antenna radiation
RF receivers433 MHz receiver module with ASK/OOK modulation, low consumption, high noise immunity and low antenna radiation
LoRa modulesBuilt around the SX1278 chip: receives down to -141 dBm and transmits at +18 dBm over SPI, with the spring antenna already fitted; runs on 3.3 volts.
RF transmittersSet consisting of an SMD 433.92 MHz transmitter module and a receiver module
RF antennasIt sits on its magnetic base and carries the signal over three metres of cable: it covers the 430 to 440 MHz band.
RF antennas
RF receiversThe CY121 is a high-performance ASK-compatible superheterodyne wireless receiver designed for the 433.92 MHz ISM band. With high sensitivity (-109 dBm), it runs on 3.6V to 5.5V and works over a wide temperature range (-20°C ~ 70°C).
